Quant al complement
Att-Hub is the central attachment manager for Thunderbird: it collects every attachment from all your mailboxes and chosen folders into a gallery – searchable, filterable, instantly at hand. The invoice as PDF? Photos, even HEIC from your iPhone? Word, Excel or a ZIP? Att-Hub renders almost any format right inside Thunderbird – 100% local, no cloud, no uploads, no extra software.
The areas at a glance – and what they do:
- The Gallery (Archive): Every attachment from all scanned folders as tiles with real preview images. Freely adjustable tile size, light and dark themes. Optionally run several tabs or windows side by side – ideal for multi-monitor setups. An interrupted folder scan can be resumed anytime – a notice shows how many attachments are still missing.
- Search & Find: Deep Search scans file names, metadata AND contents of PDFs, Office documents and text files – with relevance ranking and whole-word search via quotes ("invoice" won't hit "invoices"). Smart filters for type, sender, inbox/sent. Search history via clock icon, scroll position preserved, one click to the original mail. Ctrl+F always calls up the built-in search – system shortcuts like Ctrl+W or Ctrl+R can't reach Thunderbird while Att-Hub is active.
- The View Mode: Open the attachments of the mail you are reading instantly – no saving, no external program. Read a PDF, flip through an Office document, zoom into a photo: everything stays in the add-on.
- The Preview: PDFs, all common image formats including HEIC/HEIF, Office (DOCX, XLSX), CSV, videos, TXT/HTML, ICS, VCF – rendered locally. Plus TIFF/TGA (multi-page, with page navigation) and GAEB. Focus Mode: full screen, smooth zoom, rotation, in-document search (Ctrl+F, "word" = whole word only), DPI-selectable page snapshots.
- The Archive Browser: Browse ZIP and 7z attachments like folders – folder structure, breadcrumb clicks, ZIP-in-ZIP, password prompt, type icons.
- The Draft Mode: Accompanies you while composing – all draft attachments as a gallery. Reorder via the grip handle (edge auto-scroll), insert from clipboard or drag & drop. Optional automatic import: convert, shrink, rename. Multi-page TIFFs and animated GIFs: first page/frame or all as separate images.
- The Editor: A complete tool within the tool – for received attachments just as for drafts. Crop, rotate, draw, annotate, censor, adjust brightness/contrast/sharpness – either globally for the whole page or per selected element (Object Adjustments). Fill shapes with images (Fill/Stretch/Tile), scale proportionally, save stamp presets with colors, text and fills. And real PDFs: annotate multi-page documents, overwrite existing text by clicking it, import, insert, delete and reorder pages – save editable, semi-flattened or fully rasterized. The built-in find (Ctrl+F) locates text across all pages and highlights hits right on the page. Regions can be captured as snapshots for the clipboard – optionally rotated or as an ellipse with transparency –, inserted as objects, printed straight away or saved as a PNG file you can drag into other programs, marked elements copy across pages via Ctrl+C/X/V or the context menu, pages print in a grid layout, and the color picker samples colors with a pipette straight from the document. Eraser and clone stamp paint right onto the page – punch holes into selected objects or clone any region; a color filter with tolerance removes a chosen color precisely (cut-outs) or skips it while cloning. Both tools remember their own settings, and a reset button restores the defaults instantly. The magic wand selects image regions by click and color tolerance – refine the mask via Add/Sub/Invert, fill holes, polish the edge, then copy it as a new object, recolor it or punch it out. A color filter studio offers ten presets with live preview and a strength slider – for the whole page, just the marked image content or everything at once. The result replaces the attachment, lands as a new file in the draft, on disk or as a new mail.
- Shrink & Convert: Shrink or re-encode attachments right in the draft – JPEG/PNG/PDF output, quality in 1% steps, transparency flattening, optionally keep the originals.
- Bundle, Print, Send: Download your selection as ZIP or attach it to the draft as a ZIP file (optionally AES-256 encrypted), merge into a PDF, print single files or whole grids (visual layout picker with auto-orientation), attach straight to a new mail. Draw a quick note and attach it instantly.
- The Containers: Organize attachments via drag & drop into virtual containers – collect, back up, download, reuse.
- Your data stays yours: Everything runs locally inside Thunderbird – no uploads, no tracking. Only exotic formats (CAD/DWG/DXF, older Office formats, PPTX) can optionally go through an external viewer service of your choice – opt-in per click.
Att-Hub grew out of my own need for a better attachment workflow in Thunderbird – I use it every day. If it helps you too, even better! Questions, ideas and bug reports are welcome: thrilldroid@gmail.com
